Here are are some basic settings to get you started - with manual flash, some trial and error may be required to obtain a result to your taste.  I haven’t provided any explanations as the web will offer many detailed articles which will explain better than I can.

Set flash to full power.

Set ISO to 400

Set shutter speed to anything slower than 1/500 (1/125 or 1/250 would be sensible: the SS doesn’t actually matter).

With these settings, the guide number of your flash is 24 in metres.

Estimate (or read off the lens) the camera to subject distance and divide the GN by it.  E.g if your subject is 4 metres away, divide 24 by 4 - the result (6!) is the aperture you need to set on the camera.  It doesn’t have to be exact, f/6.3 would do perfectly well.  This will give you a good starting point for experimentation but the best flash exposure will need trial and error as all subjects differ.  If you don’t like metres, use yards instead: the difference won’t matter much at medium distances.  For fine adjustment of the exposure, alter the aperture slightly until you’re happy.  It’s this fiddling around that TTL flash avoids, giving you a good exposure with every shot.

This assumes that flash is the main light source; if you just want fill flash, dial down the power output of the flashgun until you’re happy with the result.

Hope this helps…
